It is NOT Monsterhut. It's a Single-Player Modification for UT. But I think "Mappack" is a better description than "Mod", because I use only new sounds for the Shadows (A variant of the Skaarj, which you can see at 00:45 in my video) and Mr. Tom makes the complete music for these maps, so that I don't need any retail music. Besides he makes one map (It's a Nali Village) for me. From 1:07 to 1:22 you can see the church of the village. The Mod will contain 8 to 10 maps. Of course, you can play the mod in Coop, too. A "new" weapon will include. The script for it makes Shadow. It's a Redeemer, which its firemodes are both the alternative mode of it, so that you can press switches which you cannot reach.
2009 is a good date, because I have only one third of the architecture and only I make the maps (out of Mr. Toms map). When the mod goes into beta status I can need some testers. Beta means for me: All maps are playable.
If you want something to know about the story tell it
Edit: The mod has much action. You must fight against 10 to 20 enemies at once. Naturally have the enemies less HP, otherwise you can't beat them
